Use Cases - question about the process

[Henning Sprang <henning_sprang gmx de>]

Hy,
when getting started with the UseCases documentation and analysys for 
beast some questions are raising up and I wonder if anybody has an idea 
about this


* how should a use case be documented? What questions must the 
information therein answer? maybe write these rules down here, so it's 
more clear what is the way we describe our things on this page

* if i have a UseCase, do i have everything documented that is needed to 
start writing the code that makes it happen?

* what is the difference between a requirements document, a use case 
collection and a "storyboard" for sequences of actions users want/need 
to perform to accomplish their tasks?

* is there already y formal "requirements" document for beast? is it the 
TODO file in CVS?

i appreciate every idea or comment,

Henning
